Do people really just not get it that their items are not selling...

To be able to successfully negotiate, besides knowledge and intellect, you need to acknowledge and understand the other side, another person. Not easy or simple.

Sure some is overpriced, but many are fairly priced. I find people haven't a clue. If you had new LS50 s for $500 or best offer, some moron would offer $150, thinking he's oh so clever. Just amazing
